BUILDING BLOCK.

Application fled October 81, 1923. Serial No. 672,011.

The invention relates to building structures and particularly to solid blocks which. may be made of concrete, and to structures constructed thereof.

' rovislon of an improved block which will e adaptable for use in almost. anyplace, such as walks, walls, floors and buildings generally.

Another object of my invention is the r0- vision of improved building blocks w ich will have integral interlocking means on 01)- posite walls and additional locking means on intermediate walls, all located a distance 2, which illustrate the body of the main from the edge equal to one-half of one dimension of the block. Another and further object of my invention is the provision of an improved building block having a tongue on one side, a corresponding groove on an opposite corresponding side and grooves on the intermediate sides, the tongue and grooves, each being located from the edge a dlstance equal to one-half of-one dimension. Another and still further object of my invention is the provision of an improved buildin structure comprising blocks having interlociing portions on adjacent sides in one dimension and grooves on adjacent sides in another dimension and having reinforcing rods inJthe adjacent ooves.

Another and still urther object of my invention is the provision of an improved buildin structure having an outer and inconnections between adjacent blocks extendin around the structure, grooves on vsides ad acent the courses, a beam course extending over the outer and inner walls to support the floor beams, the outer and inner walls being then extending from the beam course and spaces for the beams above the beam course and between'the blocks of the inner wall.

Referring to the drawing where I have illustrated preferred embodiments of my invention,

Figure 1 is.- aperspective 'view of the block,

Figure 2 is a cross section on the lane m bod of Figure 1 and looking ownwardly as seen in Figure 1,

Figure 3 is a cross section similar to Figure 2, but of a modified form of my invention,

A primary object of my invention is the place and reinforcing means, portions being ner wal of blocks having tongue and groove broken away to show the construction more clearly. w

The same reference characters refer to similar parts throughout the views.

Referring particularly to Figures and structural block, A designates the block as a whole. 10 designates one of the fame?" the block, 11 one of the sides being rovided with a projection which I have ll ustrated. 1n the form of,a tongue 12. Opposite the side 11 is a side 13 in which is a recess which I have illustrated in the form of a groove 14. The tongue 12 and the groove 14 of adjacent blocks are constructed in such proportions that they may 'be fitted together with only a slight space for the-cement or other binder.

In the other two sides, 15v and 16, are placed grooves 17 and 18, respectively; these grooves extending from the ends of the groove 14. to the ends of the tongue 12.

grooves are located in the middle of their respective sides. This is an important feature in order to make the block of universal use.

In Figures 3 and 4, the parts designated 10, 11, 12, 13, 14', 15-, 16', 17', and 18 are parts which correspond to the parts 10, 11, 12, 13, 14, 15, 16, 17 and 18 of Figures 1 and 2, the tongue 12 and the groove 14" being dovetail in shape.

I will now describe the in exemplary,structures.

In Figure 5 is a cross section of asidewalk made with my blocks and according to my invention, section lines for the binder being omitted for the sake of clearness.

The main portion of the structure is com-, posed of the blocks A.v At B, I have illustrated a form of corner block wherein the use of my block groove 14 is placed on what would normally be a face. This groove 14 as the groove 14, is placed at a distance, from the edge, equal to one-half of one of. the dimensions of the block. This is to insure the registration of the outside faces of the blocks A and B.

I have also illustrated a corner block C having its tongue 12 placed on what would normally be a face of the block. This tongue is placed at a distance from the edge equal to one-half of one of the dimensions of the block. This insures registration of the outside faces.

In the grooves 17 17 and 17, and the complementary grooves on adjacent blocks, is placed a reinforcing rod R which is cut to proper size and bent to proper shape.

This rod ispresent in the grooves and when embedded in the binder, furnishes a reinforcing means which is very effective to hold the whole together.

In Figure 6, I have illustrated a fragmental section of a building structure. An outer and inner wall is constructed as illustrated with an air space S therebotween. The walls are constructed of the blocks A, B and C, the blocks A and C being illustrated.

To support the floor beam or joist J, I provide a beam course of blocks which I have designated A in Figure 6. The block A adjacent the beam J is in vertical alignment with theinner wall below the beam course and is placed abutting the beam 'J to hold the latter in place. The inner wall is eontinued, the blocks abutting the beams J on both sides in each instance. The outer wall is continued upwardly in a similar manner, except that the beam J does not pass lherothrough.

In this way by using, for example, a 12 inch by 12 inch by 4 inch block, I am able to use the block for all purposes and either side up. In case a hard surface is desired to resist Water, a facing may be placed on the block either before or after the block is in place.

The rod It in Figure 6 performs a similar function to the same rod in Figure 5, in this instance it being in a horizontal plane instead of a vertical plane.

lVhile I have shown and described preferred embodiments of my invention, I desire to have it understood that these are to be considered merely as exemplary and that modifications and changes may be madel without departing from the spirit of my invention and within the scope of the appended claim.

Having described my invention, What I claim and desire to secure by Letters Patent is: v

A building block having a tongue and groove on opposite sides thereof, and in corresponding positions to register with a groove and tongue on adjacent blocks, the tongue and groove being of dovetail shape, the narrow part of the groove being wide enough to pass the narrow part of the tongue.

In testimony whereof I hereunto aflix my signature.
